Hello to each other, as described above I would have asked some questions about the complete exhaust system, i.e. from the front to the back (hosen tube to ESD). since my hosen tube and my kat have given up the spirit after 19 years, I would now like to have such an installation. now to my questions I have put together something but would like to catch up with a 2nd or 3th 4th etc. if everything would fit together at all, i.e. connections of the respective parts. hosenrohr: http://cgi.ebay.de/ws/eBayISAPI. dll?… Kat: http://cgi.ebay.de/ws/eBayISAPI.dll?… or: http://cgi.ebay.de/ws/eBayISAPI.dll?… Group A: http://cgi.ebay.de/ws/eBayISAPI.dll?… on the internet page of www.DTS.de is described that the group A system only has connection to series so I guess Kat or? what if I have this renkat of magnaflow fits then this group a in connection with the kat? have no desire to fetch with n series kat (is also too expensive in contrast) to magnaflow) . which of the two kat’s now connects the hosen tube and the group a? the group a has a 63.5mm pipe diameter. does that have to do with the connection diameter of the kat’s? would be helpful to answer many as I need this complete exhaust system intruder because so you can no longer drive around, the roars just give at the gas. thank you mfg
